CompTIA Security+ (SY0-501) — Question 851

A security analyst has been asked to implement secure protocols to prevent cleartext credentials from being transmitted over the internal network. Which of the following protocols is the security analyst MOST likely to implement? (Choose two.)

Answer options

• A. SNMPv3
• B. S/MIME
• C. DNSSEC
• D. SSH
• E. SFTP

Correct answer: D, E

Explanation

The correct answers are D (SSH) and E (SFTP) because both protocols provide secure transmission of data, including credentials, by encrypting the information. Options A (SNMPv3), B (S/MIME), and C (DNSSEC) do not primarily focus on securing credential transmission over a network.
